To all 'whom l may eoocerrfz.:

it known Ethat l, EDWARD G. Brum, e citizen. et 'the United State,residing et Pliiledelpliis, ir: 'the county of Fhiladelphie. and Stateol" Pennsylvania., have invested certain new and uselul lmproveroeiitsin Cor- Seats, of which the following is sy specilieetion. A

This imfentioo. concerns cer-seats end ses reference, more particularly,to the medien ism for supporting' the seet-lmel the proper ongle ofinclination permitting reversal tliei'eoi' from one edge oi the cushionto the otlier sud lor simulteueouslyv shifting tl'ie seet-erisliion toreise its forward edge stove .its rearward edge.

The obviect ol" the invention is to so improve the meeli emisor forsupporting the parts and reversing tl'ie facing direction of csr-seatsol the Walkover type es 'ro pro vide e. compact meclrsuisrii whichpossesses maximum strength, wliicli is so constructed thatCompsrativeljv smell force is require-d to reverse the seat, and bywhich the beek is held positively' against an im xroper moverrientthroughout the reversal thereof and in the desired relation in itsl'inel positions.

My improvements ere of particular utility in ireproor' seats in wliieliall the' parts are mede ol irietel except 'for tlie coverings of thecushions.

l lieve illustrated the preferred embodiment of my invention in the,eooiripenyirig dra-wings, in which Figure l is sri elevation of theaisle-end of 'the seat, Fig. 2 is en enlarged transverse seotiorr of eportion of the end of the seat es shown in Fig. l', Fig. 3 is enelevation of the operating' mechanism et the eislefend of the seirt esseen from the inner side, end Fig. 4 .is a top View one of the rockersfor the seetcushion.

The drawings illus rete only the mechanism for the aisle-end of the seetbut tliet at the ull-'end nie-'y be substantially vthe seme es thatslxowii, tl'rougli preferably, it is supported ori the well ol the csrinstead of the 'Hooi'.

R' the sont is supported ou in, metzrllio cricket consisting; ol twosubstantially similer ports, esi-cli lowing o liodjV l und e leg 2, theadjeoent of tlie former being secured to` retirer sud the erids oi theletter being secured 'to tlie vliloor. At its upper end, this Ierrlug tothe d1mvings,.tlie`aisle-end of cricket is provided with integra-lsriges on which are secured the ends or two com-lectin rails S. To theende of these mils ere liolt e' end connectors or sockets Il toiwhieliis 'seeured s remeplete 5. This plete formed to provide e eem surfaceoft peculiar oorifformation for supporting and guiding e beeksuppertingerm es lie 'eine-iter described; this preferably done by cutting e, slotin the, plete the ro 'or portion, @,Fof Wh'loli is formed ori an are oflarge radius sud et the erids of the portion 6 sitedormWsrdlyF-exteudirrg end portions 7 oud At the lower edge olf theportion. of the slot md et equal distantes from tlie ends 7 sind S aretwo rounded eut- :r 'portions 9 endl G. ivotel'ly mounted upon the innerside ol plate ere one or more rollers Whose upper surfaces eresulistenti'sy ilusli. 'with the lower edge of the slot in tlie plate; inthe drawings, ,l have shown two suoli, rollers 1l mounted between andClose to the offsets 9 and 1G of the slot.

The slot iu plate 5 is adapted to receive and guide two rollers l2 and13 pivotally moi-mted on alle lower erid of e beck-supporting erm lewhich moves backend fortl'i. adjacent to the plete 5. This erm extendsupward and is seeured at its upper end to the beekousllioir 27 of theseat, a socket-plete l5 being secured over 'the upper end ol" erm lll.The lower end of arnoY lll is of eonsidereble width and the roll l2 and13 thereon are et e distance apart equal tothe distance be tween eitherend of the slot in plete 5 :md the oifset 9 or l() adjacent thereto.

ln the plete 5 is e central opening termin a bearing for the end of e.rod 16 and seoure on this rod is s lever 1'2". The end of this leverextends up adjacent to erro 14l arid is provided with o, pin .1.8Wlilcli extends through en elongated slot in erm lll. This piu hes enenlarged head to prevent the pin rom slipping through the slot, thisheed lieiiig flattened on opposite sides to permit of readily assemblingend disassemblirlg the parts.' Below the rod i6, lever 17 is bent iu'Wordly of the seet and its lower end is provided with e segmental gear19. This gear meshes with e rack ZO on the rocker 21 for thesent-cushion 22. Rooker 2l is mounted to slide beek and forth inrooker-runslormed in the sockets or end ooriiiectors Il and on its loweredge. lies oem surfaces Wliioli serve to alter the angular relation o??the rocker es it mores lu the welter-runs. 0n its upper to enter holesin the 1.3 lying in the cutaway portion 10.

edge, the rocker has dowelpins 24 adapted under side of the seatcushiontrarne to support the cushion and move it as the rockers are moved.

In Fig, 4, a top view of the rocker 21 is shown, om which it will beseen that the teeth of the rack 20 are separately formed and projectfrom the side ofthe rocker vso that dust cannot settle in and partiallyll the spaces between them and prevent smooth working of the parts.

A cover-plate 25 of metal is secured in any suitable manner on the outerside of plate 5 over the slot therein and serves to hold the parts ofthe plate against relative movement under the strains to which they aresubjected. A seat-end 26 is secured to plate 5 to conceal the operatingmechanism and extends upward above the plane of the seatcushion, itsupper edge supporting an armrest. This seat-end is preferably formed ofsheet-metal and is of attractive design.

The operation of the seat as thus constructed will now be described.

-In the position of the parts shown in Figs'. 1 and 3, the back 27 issupported by the rollers 12 and 13 on the back-supporting arm 14 bearingon the cam surface formed by the lower edge of the slot in plate 5, theroller 12 lying -at the bottom of the down- Wardlyeturned end portion 8and the roller The back is held at the proper inclination with relationto the vertical as the roller 13 is above the roller 12. In reversingthe facing direction of the seat, force is applied to the back in thehorizontal direction. At the beginning of the movement of the back, therollers 12 and 13-ride up on the lower in clined edges of the end 8 andthe oilset 10, respectively, of the slot in plate 5, these edges beingarranged to diverge somewhat in the upward direction, and the back israised slightly and turned angularly to appreach the vertical moreclosely. When rollers 12 and 13 are in the substantially ilat portion 6of the slot, the movement ol the back is practically a horizontal one sothat very little force is required to move it, this being furtherdecreased by the anti-friction roller or rollers 11 which are engaged bythe lower edge of arm 14 and, to a large extent,- take the weight ol'the back oiil rollers 12 and 13. As the back moves along, the coactionof pin 18 with the slot in arm 14 turns lever 17 and the rod 1G to whichit is secured, the pin 18 moving to the upper end of the slot and backagain to the lower end during the reversal of the back. W hen roller 12is directly over the o'll'set l() in the slot in'plate 5, there is nodownward movement of the back such as would carry the reller into theoffset since the-roller 11 adjacent to the oli'- set is in engagementwith the bottom of arm 14 and supports the latter. vSimilarly the roller13 is prevented from moving into oil"- set 9 by the roller 11 adjacentto that offset. l/Vhile the rollers are moving across the portion 6 ofthe slot, which is, curved on an arc of large radius, the angularrelation of the back with reference to the vertical is changed slightlyand when roller 13 reaches the end of the portion 6 it moves downto theend ofthe downwardly-turned portion 7 g at the same time, roller 12moves down to the end of the offset 9 and the back is in its finalposition.

It will be seen that the sides of the olisets 9 and 10 adjacent to theends of plate 5 are curved over to form projections indicated at 28,Fig. 3, under which the roller on arm 14 will lie when it is at thebottom of the oliset and the back is in its final position. 'lhecoaction of pin 18 with the slot in arm 14 precludes such movement ofthe back as will cause roller 12 to lodge on top of the projection 28,'as above stated, pin 18 moves to the top and thenl down again to thebottom of the slot during the reversal of the back and it reaches thelower end as thev roller l2 ap` preaches a position over projection 28,thus down into oil'set .0, and while doing this, pin

. of gear 1Q and rack 2() causes i 18 moves away from the bottom ol 'inarm 1-1 a very slight distance. But when roller 12 is in its finalposition at the bottom of slot 9, the )rejection 28 extends so fararound the roller as to preclude any movement thereol" under the weightol' lhe occupant of the seat against the bark. 'lhe other roller 13rests in the bottom of the end portion 7 and therefore the bach islirmlyr held in its operative position. 'llhe coaction novement ol rocters 2l and the seat-cushion carried thereby as the backis moved, in adirection opposite to the direction of movement oli the back and the camsurfaces 22% on the rockers' operate to raise the [forward edge of theseat above its rearward edge.- Rod 1l (i to which the levers 17 at bothends ot' the seat are secured serves to synchronize the movementsat'hoth ends of the seat.

.lt will be seen that the mechanism ol'` the seat as tlms constructi-*dis verycompactly|` arranged and that on account ol the. shape ol theIslot in plate 5 with the major portion tl'lereol" `curved on an arc ollong radius, the plate can be of com )aratively small width. Thisshaping ol`- thel slot gives the `further advantage that the back israised'vertically 'only a small yextent in reversing, andtherefore asmall amount ol' vtorce is required to reverse the seat.

llaving now describedV my invention, what I claim new therein and desiretosecure by Letters Patent is as lollows:

1. ln a reversible car-seat, the combination, of a frame, a movableback, a backsupporting arm, a cam. surface on said frame precludingfurther movement in this direction.
